Tin bronze pump body casting

The main function of the pump cover is to seal and tighten. Ensure the normal work of the oil pump and no oil leakage. Therefore, the pump cover has good flexibility and good alignment.
The pump body is composed of water suction chamber and pressurized water chamber.Read More

The valve cover is a valve part with stem seal, which is used to connect or support the executing agency. The valve cover and valve body can be a whole, and also can be separated.
Different control valve structure and use requirements need to have the corresponding upper valve cover. The upper valve cover is filled with stuffing box to seal the stem and the stem extends through it. The upper cover is threaded or bolted in the form of the actuator, which is the same as the valve body, also withstanding the pressure of the medium, temperature and corrosion.Read More

The check valve is automatically opened and closed by the force generated by the flow of the medium in the pipeline, and belongs to an automatic valve. Check valve is used for pipeline system. Its main function is to prevent the media flowing backwards and bleeding from the container. Check valves may also be used for piping where the pressure may be increased to the auxiliary system that exceeds the main system pressure.Read More

The pump body is composed of water suction chamber and pressurized water chamber. The inlet of the water suction chamber and the outlet of the pressurized water chamber are the pump inlet flange and outlet flange, which are used to connect the inlet pipe and the outlet pipe. The water suction chamber is generally a cone-shaped nozzle stub or isometric straight pipe, which is used to lead the water flow into the impeller and provide the required flow pattern to the impeller. The role of the pressurized water chamber is to collect the liquid from the impeller and lead the flow to the outlet. The outer shape of the pressurized water chamber is very much like a snail shell, commonly known as the volute. And the impeller is wrapped in the volute.Read More

The water pump impeller is made of cast iron. The blades on the water pump impeller also play a major role. The shape and size of the pump impeller are closely related to the water pump performance. The water pump impeller can be divided into single suction type and double suction type. Single suction impeller is for unilateral suction, and most small flow water pump impeller is this type. Double suction impeller is for both suction water, and large flow water pump impellers all use the double suction impeller. Open impeller only has blade and blade reinforcement, without front and rear cover of the impeller. The number of open impeller blades is less , about 2-5. The water pump impeller is low efficiency and less application, which is mainly used to transport high viscosity liquid and syrupy liquid .Read More

The valve disk is the valve core, which is one of the main core parts of the valve. It directly bears the pressure of the medium in the valve . The materials used must comply with the " pressure and temperature grades of the valve ". Each disk has a cylindrical bore with a transfer shaft and a ring groove or sealing surface mounted with a sealing ring. According to the use of the valve disk, the valve material can be cast iron, carbon steel and stainless steel. The blanks are all castings.Read More

Castings of such material have good abrasion resistance, corrosion resistance and air tightness; high mechanical properties and pressure resistant performance; easy cutting and processing.
The material standard complies with ASTM B148.Read More

Valve body is one of the main components in the valve and has different mechanical manufacturing methods according to the pressure grade. Valve body is the valve core part of the valve, mainly used in the water valve and air valve, which is used in the interior of the valve to obstruct water flow or air flow. Commonly used materials are: cast iron, cast steel, stainless steel, carbon steel, plastic, copper and so on.Read More
